Sažetak
Iron (Fe) is an essential micronutrient for strawberries and a component of many vital plant enzymes. It plays a critical role in plant metabolic processes such as DNA synthesis, respiration, and photosynthesis. Fertigation is a common practice in strawberry cultivation, where minerals are supplied through a solution that is distributed in the root zone of the plants. At some critical stages of the plant, certain nutrients are needed in larger quantities to achieve higher yield and excellent fruit quality. Therefore, it is necessary to supply the nutrients through foliar application, as the roots are not able to take up sufficient amounts of nutrients. Experiments were conducted in spring 2021 near Zagreb (Croatia) with short-day strawberry (Fragaria × ananassa Duch.) cultivar 'Joly' grown on soilless media. Foliar iron - Fe-EDDHA solutions were applied in two different treatments: 1) Fe-EDDHA solutions 10 mL Fe-EDDHA 6% (Poly-Feed™) solution once at the beginning of flowering and 2) Fe-EDDHA solutions 10 mL Fe-EDDHA 6% (Poly-Feed™) solution once at the beginning of flowering and a second time at full bloom. Harvested fruits were analyzed for physicochemical properties (weight, dry matter, firmness, pH, total soluble solids, and total acidity) and mineral composition (N, P, K, Fe, Zn, Mn, Cu). Foliar treatment with Fe-EDDHA significantly reduced the acidity and improved the sweetness of the fruits compared to the fruits of the untreated plants (control). Treatment with Fe-EDDHA increased dry matter and had no positive effect on the increase of Fe content in fruits, only Zn, Mn and Cu showed some decrease.
